When Super Junior vocalist Shindong accepted the gig as the host of the "Idol Star Athletics Championship," he couldn't have expected this extra perk.

On Tuesday's broadcast of the South Korean television program "Beatles Code 3D" Shindong explained the invaluable lesson he learned at the celebrity athletic competition.

"There is this certain pose that the members of girl groups do," Shindong said.

"First the female pop star member leans on her closest bandmate and starts twisting her body near a boy idol. If you watch her closely, she starts making eye contact with the male pop star that she's near. And then I find out [in each case] the two are dating and there are already rumors about them."

When Shindong, who also hosts "Beatles Code," looked over at his guests, the six-member K-pop boy band VIXX they were speechless.

"Why are you guys all frozen?" he asked. "Why did you put your hands together when you didn't do anything wrong?"

Known for his provocative interview questions the Shindong put VIXX on the defensive when he made the assertion the notion that the meteoric success of rival K-pop group Exo has hurt their career.

"Do you think the fact that your popularity has not increased even more than it has was because of EXO?" asked the Super Junior singer.

VIXX frontman N, shot down the suggestion, while his bandmate Ravi admitted it is possible that Exo, the first Korean group in 12 years to sell one million albums in one year in 2013, could have stolen some of their band's thunder.

But he likes the idea of how loyal that makes the fans they currently have.

"Exo are close friends of ours and our promotions often overlapped," Ravi said.

"If there was no Exo, there is the possibility that the interest that they attracted could have been directed toward us. However, we are promoting with the thought that the people who love us, will always love us."
